| Summary of Significant Accounting Policies | 3. Summary of Significant Accounting Policies
(a) Basis of Presentation The consolidated financial statements
of the Group are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
(b) Reclassification Certain prior year amounts in the consolidated
financial statements have been reclassified to conform with the current year presentation. These reclassifications have not changed the
results of operations of prior year.
(c) Principles of Consolidation The consolidated financial statements
include the financial statements of the Group, and its subsidiaries. All material inter-Group transactions and balances have been eliminated
upon consolidation. For consolidated subsidiaries where the Group’s ownership in the subsidiary is less than 100%, the equity interest
not held by the Group is shown as noncontrolling interests. The Group accounts for investments over which it has significant influence
but not a controlling financial interest using the equity method of accounting. The Group deconsolidates a subsidiary when the Group ceases
to have a controlling financial interest in the subsidiary. When control is lost, the parent-subsidiary relationship no longer exists
and the parent derecognizes the assets and liabilities of the subsidiary.
(d) Use of Estimates The preparation of the financial statements
in conformity with U.S. GAAP requires the Group to make estimates and assumptions that affect reported amounts of assets and liabilities
and disclosure of contingent assets and liabilities at the date of the consolidated financial statements as well as the reported amounts
of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant accounting estimates
reflected in the Group’s consolidated financial statements include the allowance for doubtful accounts receivable and other receivable,
the impairment of goodwill and long-lived assets, fair value of derivative liability and share based compensation. Changes in facts and
circumstances may result in revised estimates. The current economic environment has increased the degree of uncertainty inherent in those
estimates and assumptions.
(e) Foreign Currency Translation and Foreign Currency Risk The functional currency of the Group
and subsidiaries located in the United States is the United States dollar (“US$” or “$”). The functional currency
of the Group’s subsidiaries located in the Hong Kong, Europe, United Kingdom, Japan, Canada and Australia are Hong Kong Dollar (“HKD”),
EURO (“EUR”), British Pounds(“GBP”), Japanese Yen (“JPY”), Canadian Dollar (“CAD”) and
Australia Dollar (“AUD”), respectively. Transactions denominated in foreign currencies are re-measured into the functional
currency at the rates of exchange prevailing when the transactions occur. Monetary assets and liabilities denominated in foreign currencies
are re-measured into the functional currency at rates of exchange in effect at the balance sheet dates. Exchange gains and losses are
included in the consolidated statements of operations. The Group’s reporting currency
is the US$. Assets and liabilities of subsidiaries, whose functional currency is not the US$, are translated into US$ using exchange rates
in effect at each period end, and revenues and expenses are translated into US$ at average rates prevailing during the year, and equity
is translated at historical exchange rates, except for the change in retained earnings during the year which is the result of the income
or loss. Gains and losses resulting from the translations of the financial statements of these subsidiaries into US$ are recognized as
other comprehensive income or loss in the consolidated statement of comprehensive loss.
(f) Fair Value of Financial Instruments The Group measures at fair value certain
of its financial and non-financial assets and liabilities by using a fair value hierarchy that prioritizes the inputs to valuation techniques
used to measure fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly
transaction between market participants at the measurement date, essentially an exit price, based on the highest and best use of the asset
or liability. The levels of the fair value hierarchy are:
Ÿ Level 1 — Quoted market prices in active markets for identical assets or liabilities.
Ÿ Level 2 — Significant other observable inputs (e.g., quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable, such as interest rate and yield curves, and market-corroborated inputs).
Ÿ Level 3 — Unobservable inputs in which there is little or no market data, which require the reporting unit to develop its own assumptions. The Group uses quoted market prices
to determine the fair value when available. If quoted market prices are not available, the Group measures fair value using valuation techniques
that use, when possible, current market-based or independently-sourced market parameters, such as interest rates and currency rates.
(g) Business Combination Business combinations are recorded
using the acquisition method of accounting and, accordingly, the acquired assets and liabilities are recorded at their fair market value
at the date of acquisition. Any excess of acquisition cost over the fair value of the acquired assets and liabilities, including identifiable
intangible assets, is recorded as goodwill. The Group charges acquisition related costs that are not part of the purchase price consideration
to general and administrative expenses as they are incurred. Those costs typically include transaction and integration costs, such as
legal, accounting, and other professional fees. The Group evaluates whether a transaction
should be accounted for as an acquisition and/or disposal of a business versus assets. In order for a purchase to be considered an acquisition
of a business, and receive business combination accounting treatment, the set of transferred assets and activities must include, at a
minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. If substantially
all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets,
then the set of transferred assets and activities is not a business. The adoption of this standard requires future purchases to be evaluated
under the new framework.
(h) Asset Acquisition When the Group acquires other entities,
if the assets acquired and liabilities assumed do not constitute a business, the transaction is accounted for as an asset acquisition.
Assets are recognized based on the cost, which generally includes the transaction costs of the asset acquisition, and no gain or loss
is recognized unless the fair value of noncash assets given as consideration differs from the assets’ carrying amounts on the Group’s
books. If the consideration given is not in the form of cash (that is, in the form of noncash assets, liabilities incurred, or equity
interest issued), measurement is based on either the cost to the acquiring entity or the fair value of the assets (or net assets) acquired,
whichever is more clearly evident and, thus, more reliably measurable. The cost of a group of assets acquired in an asset acquisition
is allocated to the individual assets acquired or liabilities assumed based on their relative fair value and does not give rise to goodwill.
(i) Cash and Cash Equivalents Cash and cash equivalents include cash
on hand, cash accounts, interest bearing savings accounts and all highly liquid investments with original maturities of three months or
less, and which are unrestricted as to withdrawal and use. There were no
(j) Restricted Cash Restricted cash represent bank deposits
with designated use, which cannot be withdrawn without certain approval or notice. As of December 31, 2022, the
Group had restricted bank deposits of $ 7,454 5,491 542 710 461 250 As of December 31, 2021, the Group
had restricted bank deposits of $ 8,080 6,140 1,940
(k) Accounts Receivable, net The Group grants open credit terms
to credit-worthy customers. Accounts receivable are primarily related to the Group's sales of PV components, revenue from roofing and
solar energy systems installation, electricity revenue with PPA, sales of solar modules and sales of EVs and forklifts. The Group maintains allowances for
credit losses for estimated losses resulting from the inability of its customers to make required payments. Accounts receivable is considered
past due based on its contractual terms. In establishing the allowance, management considers historical losses, the financial condition,
the accounts receivables aging, the payment patterns and the forecasted information in pooling basis upon the use of the Current Expected
Credit Loss Model (“CECL Model”) in accordance with ASC topic 326, Financial Instruments - Credit Losses. Accounts receivable
that are deemed to be uncollectible are charged off against the allowance after all means of collection have been exhausted and the potential
for recovery is considered remote. There is a time lag between when the Group estimates a portion of or the entire account balances to
be uncollectible and when a write off of the account balances is taken. The Group does not have any off-balance-sheet credit exposure
related to its customers. Contractually, the Group may charge interest for extended payment terms and require collateral.
(l) Inventories Inventories are stated at the lower
of cost or net realizable value. The cost of raw materials is determined on the basis of weighted average cost method. The cost of finished
goods is determined on the basis of weighted average and comprises direct materials, direct labor and an appropriate proportion of overhead.
Net realizable value is based on estimated selling prices less selling expenses and any further costs expected to be incurred for completion.
Adjustments to reduce the cost of inventory to net realizable value are made, for estimated excess, obsolescence, or impaired balances
if any.
(m) Project Assets The Group acquires or constructs PV
solar power systems (“solar system”) that are (i) held for development and sale or (ii) held for the Group’s own use
to generate income or return from the use of the solar systems. Solar systems are classified as either held for development and sale within
“project assets” or as held for use within “property and equipment” based on the Group’s intended use of
solar systems. The Group determines the intended use of the solar systems upon acquisition or commencement of project construction. Classification of the solar systems
affects the accounting and presentation in the consolidated financial statements. Transactions related to the solar systems held for development
and sale within “project assets” are classified as operating activities in the consolidated statements of cash flows and reported
as sales and costs of goods sold in the consolidated statements of operations upon the sale of the solar systems and fulfillment of the
relevant recognition criteria. Incidental electricity income generated from the solar systems held for development and sale prior to the
sale of the projects is recorded in other income (loss) in the consolidated statement of operations. The solar systems held for use within
“property and equipment” are used by the Group in its operations to generate income or a return from the use of the assets.
Income generated from the solar systems held for use are included in net revenues in the consolidated statement of operations. The costs
to construct solar systems intended to be held for own use are capitalized and reported within property and equipment on the consolidated
balance sheets and are presented as cash outflows from investing activities in the consolidated statements of cash flows. The proceeds
from disposal of solar systems classified as held for own use are presented as cash inflows from investing activities within the consolidated
statements of cash flows. A net gain or loss upon the disposal of solar systems classified as held for own use is reported in other income
(loss) in the consolidated statement of operation. Solar systems costs consist primarily
of capitalizable costs for items such as permits and licenses, acquired land or land use rights, and work-in-process. Work-in-process
includes materials and modules, construction, installation and labor, capitalized interests and other capitalizable costs incurred to
construct the PV solar power systems. The solar systems held for
development and sale, named as “project assets”, are reported as current assets on the consolidated balance sheets when
upon completion of the construction of the solar systems, the Group initiates a plan to actively market the project assets for
immediate sale in their present condition to potential third party buyers subject to terms that are usual and customary for sales of
these types of assets and it is probable that the project assets will be sold within one year. Otherwise, the project assets are
reported as noncurrent assets. No depreciation expense is recognized while the project assets are under construction or classified
as held for sale. For solar systems held for development
and sale, named as “project assets”, the Group considers a project commercially viable if it is anticipated to be sold for
a profit once it is either fully developed or fully constructed. The Group also considers a partially developed or partially constructed
project commercially viable if the anticipated selling price is higher than the carrying value of the related project assets plus the
estimated cost to completion. The Group considers a number of factors, including changes in environmental, ecological, permitting, market
pricing or regulatory conditions that affect the project. Such changes may cause the cost of the project to increase or the selling price
of the project to decrease. The Group records an impairment loss of the project asset to the extent the carrying value exceed its estimated
recoverable amount. The recoverable amount is estimated based on the anticipated sales proceeds reduced by estimated cost to complete
such sales. Subsequent reversal of a previously recognized impairment loss is prohibited once the measurement of that loss is recognized. If the Group’s intended use of
solar systems changed from held for development and sale within “project assets” to held for use within “property and
equipment”, the solar systems should be measured in accordance with ASC 360-10-35-44 at the lower of (1) its carrying amount before
the asset was classified as held for development and sale, adjusted for any depreciation or amortization expense that would have been
recognized had the assets continued to be classified as held for use, or (2) the fair value at the date of the subsequent decision not
to sell. Any adjustment to the carrying amount based on reclassifying the solar systems to held for use within “property and equipment”
should be reflected in the income statement within continuing operations in the period the decision is made not to sell.
(n) Property and Equipment, net The Group accounts for its property
and equipment at cost, less accumulated depreciation and any impairment. Cost includes the prices paid to acquire or construct the assets,
interest capitalized during the construction period and any expenditure that substantially extends the useful life of an existing asset.
The Group expenses repair and maintenance costs when they are incurred. Depreciation is recorded on the straight-line method based on
the estimated useful lives of the assets as follows:
Schedule of estimated useful lives of property, plant and equipment
Furniture, fixtures and equipment 5, 7 or 10 years
Automobile 3, 5 or 7 years
Bitcoin mining equipment 3 years
Leasehold improvements The shorter of the estimated life or the lease term
PV solar system 20 or 25 years
Plant equipment 7 years
(o) Intangible Assets other than Goodwill, net Intangible assets consist of customer
relationships, technology, patents and other. Amortization is recorded on the straight-line method based on the estimated useful lives
of the assets.
(p) Impairment of Long-lived Assets The Group’s long-lived assets
include property and equipment, project assets, right-of-use assets and other intangible assets with finite lives. The Group evaluates
long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be
recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Group first compare undiscounted
cash flows expected to be generated by that asset or asset group from its use and eventual disposition to its carrying amount. If the
carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized
to the extent that the carrying amount exceeds its fair value. Fair value is determined through various valuation techniques including
discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. Any impairment write-downs
would be treated as permanent reductions in the carrying amounts of the assets and a charge to statement of operations would be recognized.
As described in Note 7 and Note 21, the Company recorded impairment on project assets and right of use assets of $ 1,955
nil
(q) Goodwill Goodwill represents the excess of the
purchase consideration over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed of the
acquired entity as a result of the Group’s acquisitions of interests in its subsidiaries. Goodwill is not amortized but is tested
for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that it might be impaired. The Group
has an option to first assess qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment
test. In the qualitative assessment, the Group considers primary factors such as industry and market considerations, overall financial
performance of the reporting unit, and other specific information related to the operations. Based on the qualitative assessment, if it
is more likely than not that the fair value of each reporting unit is less than the carrying amount, the quantitative impairment test
is performed. In performing the quantitative impairment
test, the Group compares the fair values of each reporting unit to its carrying amount, including goodwill. If the fair value of each
reporting unit exceeds its carrying amount, goodwill is not considered to be impaired. If the carrying amount of a reporting unit exceeds
its fair value, the Group recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s
fair value; the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Application of a goodwill
impairment test requires significant management judgment, including the identification of reporting units, assigning assets, liabilities
and goodwill to reporting units, and determining the fair value of each reporting unit. The judgment in estimating the fair value of reporting
units includes estimating future cash flows, determining appropriate discount rates and making other assumptions. Changes in these estimates
and assumptions could materially affect the determination of fair value for each reporting unit. There is no
(r) Income Taxes The Group accounts for income taxes
under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable
to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and
operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply
to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance
is recognized if it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. The Group recognizes in the consolidated
financial statements the impact of a tax position, if that position is more likely than not of being sustained upon examination, based
on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold,
management presumes that the position will be examined by the appropriate taxing authority that has full knowledge of all relevant information.
In addition, a tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to
be recognized in the financial statements. The tax position is measured at the largest amount of benefit that is greater than 50 percent
likely of being realized upon settlement. The Group’s tax liability associated with unrecognized tax benefits is adjusted periodically
due to changing circumstances, such as the progress of the tax audits, case law developments and new or emerging legislation. Such adjustments
are recognized entirely in the period in which they are identified. The Group records interest and penalties related to an uncertain tax
position, if and when required, as part of income tax expense in the consolidated statements of operations. No reserve for uncertainty
tax position was recorded by the Group for the years ended December 31, 2022 and 2021. The Group does not expect that the assessment
regarding unrecognized tax positions will materially change over the next 12 months. The Group is not currently under examination by an
income tax authority, nor have been notified that an examination is contemplated.
(s) Revenue Recognition The Group adopted Accounting Standards
Codification (“ASC”) No. 606, “Revenue from Contracts with Customers” (“ASC 606” or “Topic 606”).
The Group’s accounting practices under ASC Topic 606 are as followings: The Group generates revenue from sales
of PV components, roofing and solar energy systems installation, electricity revenue with Power Purchase Agreements (“PPAs”),
sales of PV project assets, sales and leasing of EV and others for the years ended December 31, 2022 and 2021. Sale of PV components Revenue on sale of PV components includes
one performance obligation of delivering the products and the revenue is recognized at a point in time following the transfer of control
of such products to the customer, which typically occurs upon shipment or acceptance of the customer depending on the terms of the underlying
contracts. Revenue from roofing and solar energy systems installation
Revenue from roofing and solar energy
system installation is recognized over time. For revenue from solar energy system
installation, the Group’s only performance obligation is to design and install a customized solar energy system, or to reinstall
the customer’s existing solar energy system. For revenue from roofing, the Group’s only performance obligation is to design
and build the roof system per customer specifications. The Group’s roofing projects
involve the construction of a specific roof systems in accordance with each customer’s selection; the Group’s solar energy
system installations involve solar modules being retrofitted to existing consumer roofs using rails, then connected to the utility using
an inverter system. For both solar energy system installation and roofing, typically jobs are completed within three months, the specific
timing depends on the size of the job and the complexity of the job site, and the contract price includes all material and labor needed,
and payments are collected based on specific milestones. The Group provides solar energy systems
and roofing installation for various customers, such as homeowners and real estate developers, but the design and installation for each
customer differs substantially on the basis of each customer’s needs and the type of shingle or roof that is placed with the solar
energy system. The asset consequently has no alternative use to the Group because the customer specific design limits the Group’s
practical ability to readily direct the solar energy system to another customer. As such the Group’s performance does not create
an asset with an alternative use to the Group. Pursuant to the contract, the customers agree to pay for any costs, expenses and losses
incurred by the Group upon termination, and therefore, revenue is recognized over time according to ASC 606-10-25-27(c). For both solar energy system installation
and roofing, all costs to obtain and fulfill contracts associated with system sales and other product sales are expensed to cost of revenue
when the corresponding revenue is recognized. The Group recognizes revenue using
a cost-based input method that recognizes revenue and gross profit as work is performed based on the relationship between actual costs
incurred compared to the total estimated cost of the contract, to determine the Group’s progress towards contract completion and
to calculate the corresponding amount of revenue and gross profit to recognize. The total estimated cost of the contract constitutes of
material cost and labor cost, and are developed based on the size and specific situation of different jobs. Changes in estimates mainly
due to: (i) unforeseen field conditions that impacts the estimated workload, and (ii) change of the unit price of material or labor cost. If the estimated total costs on any
contract are greater than the net contract revenues, the Group recognizes the entire estimated loss in the period the loss becomes known. Electricity revenue with PPAs The Group sells energy generated by
PV solar power systems under PPAs. For energy sold under PPAs, the Group recognizes revenue each period based on the volume of energy
delivered to the customer (i.e., the PPAs off-taker) and the price stated in the PPAs. The Group has determined that none of the PPAs
contains a lease since (i) the purchaser does not have the rights to operate the PV solar power systems, (ii) the purchaser does not have
the rights to control physical access to the PV solar power systems, and (iii) the price that the purchaser pays is at a fixed price per
unit of output. Sale of PV project asset The Group’s sales arrangements
for PV projects do not contain any forms of continuing involvement that may affect the revenue or profit recognition of the transactions,
nor any variable considerations for energy performance guarantees, minimum electricity end subscription commitments. The Group therefore
determined its single performance obligation to the customer is the sale of a completed solar project. The Group recognizes revenue for
sales of solar projects at a point in time after the solar project has been grid connected and the customer obtains control of the solar
project. Revenue from sales and leasing of EV The Group recognizes revenue from sales
of EV at a point in time following the transfer of control of such products to the customer, which typically occurs upon the delivery
to the customer for EV sales. The Group determined that the government grants related to sales of EV should be considered as part of the
transaction price because it is granted to the EV buyer and the buyer remains liable for such amount in the event the grants were not
received by the Group or returned due to the buyer violates the government grant terms and conditions. EV leasing revenue includes revenue
recognized under lease accounting guidance for direct leasing programs. The Group accounts for these leasing transactions as operating
leases under ASC 842 Leases, and revenues are recognized on a straight-line basis over the contractual term. Other revenue Other revenue mainly consist of sales
of self-assembled solar modules, sales of component and charging stations, sales of forklifts, engineering and maintenance service, shipping
and delivery service, sales of pre-development solar projects and others. Other revenues are recognized at a point in time following the
transfer of control of such service or products to the customer, which typically occurs upon shipment of product or acceptance of the
customer depending on the terms of the underlying contracts. Disaggregation of revenues The following table illustrates the
disaggregation of revenue by revenue stream for the years ended December 31, 2022 and 2021:

Advance from customers $ 8,634 $ 4,210 The contract assets primarily relate
to the Group’s rights to consideration for work completed but not billed at the reporting date, primarily for the revenue from roofing
and solar energy systems installation in the United States. The contract assets are transferred to receivables when the rights become
unconditional after billing is issued. Advance from customers, which representing
a contract liability, represents mostly unrecognized revenue amount received from customers. Advance from customers is recognized as (or
when) the Group performs under the contract. During the years ended December 31, 2022 and 2021, the Group recognized $ 4,210 1,377 (t) Government Grant The Group receives grants from
